(Cl. 12S-13) 4 Claims.

This invention relates to new and useful improvements in a double adjustable binder.

The invention proposes certain improvements in a binder having a back, and separate front and back covers having their inner edge portions extending over the inner faces and sides of said back. The improvements include a rib on the inner face of said back between the sides thereof and extending inward between the inner edges of said covers. It is proposed that transverse studs for passing through perforations of pages for said binder be mounted in said rib. It is proposed that angle irons on iiexible strips be mounted on the inner edge portion of said covers for extending over the back corners of the pages of said binder and for extending over the ends of said studs. It is also proposed that fastening elements be mounted on said studs for securing said flexible strips in position. Furthermore, it is proposed t provide certain of the arms ofthe said angle irons with. stacking pins for engageing perforations of the pages of the binder.

Another object of the invention resides in the provision of means for releasably Securing the inner edges of said exible strips on the sides of said rib.

For further comprehension of the invention, and of the objects` and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure- Fig. 1 is a perspective View of a binder constructed in accordance with this invention and viewed from the back.

Fig. 2 is a perspective view of the binder shown in Fig. 1 but looking from the front.

Fig. 3 is a fragmentary horizontal enlarged sectional view taken on the line 3 3 of Fig. 2.

Fig. 4 is a fragmentary vertical sectional View taken on the line liof Fig. 3.

Fig. 5 is a view similar to Fig. 3 but with the connecting strips removed.

Fig. 6 is a perspective view -of one of the studs used in the binder.

Fig. 7 is a perspective view of another stud for the binder.

The double adjustable binder, in accordance with this invention, has a back I0, and separate front and back covers II and l2 respectively. These covers have their inner edge portions IIa and I2, respectively, extended over the inner face and sides of the back I0. A rib I3 is on the inner face of the back It and is located between the sides thereof, preferably intermediate of the width of the bach. This rib I3 extends inward, in between the inner edge portions IIa and I2a of the covers. The back li) is ornamented with a sheet leather covering ifi, or other decorative material. Y

A plurality of transverse studs i5 for passing through perforations iii in pages il for the binder, are mounted on the said rib I3. Each stud I5 is formed from two sections connected together. rIhere is a right hand section I having a reduced threaded end IB which passes through an opening in the rib i3 and which threadedly engages a tubular left hand section Zii. The sections I8 and 20 are formed with several radial perforations 2| into which a nail or other tool may be engaged for conveniently gripping the sections so that they may be turned to engage or clisengage the threads of the stud i5.

The inner edge portions ila and Ia of the covers are joined with the material of the covers by flexible portions at the points 22. Angle members Sii are mounted by one of their arms, their base arms, upon the edge portions IIa and I2a of the covers so that their other arms, their vextended arms, may extend along the outer faces of the pages il of the binder. The extended arms oi the angle members 3) also extend over the free ends of the studs I5. Fastening elements, such as headed screws 23, are mounted through apertures Sd in the extended arms of the angle members 3B and threadedly engage the outer ends oi the studs l5 to rigidly hold the angle members 30 in position relative to the `back II). It should be noted that the covers II `and I2 may be opened and closed because of the ilexible portions 22. The extended arms of the angle members 3E) are also provided with several inwardly projecting stacking pins 2d which engage additional perforations I6 in the pages il.

The covers I I and I2 are each constructed with several internal stiffening layers 3l which are encased by an outer covering sheet 32 and an'inner covering sheet 33. The outer covering sheet 32 continues past the inner edge of the stiifening sheets 3l and continues around the base arms of the angle members 3) terminating at the points 32a.

Covering strips 3G are mounted over the extended arms of the angle members te and continue over the inner edge portions of the stiiening layers 3l and terminates at the points 34a. The inner covering sheets 33 engage over the edge portions of the stiffening layers 3| at the points 348, as clearly seen for example, in Fig. 3.

Means is provided for releasably securing the inner edges of the covers onto the sides of the rib I3. 'Ihis means is shown to comprise a plurality of spacer strips 26 extending substantially the height of the back it and connected with the sides of the rib i3 and with the inner edges of the covers Il and l 2. The spacer strips 26 are provided with dove-tailed tongues 2l on one of their sides which engage complementary grooves, either upon the sides of the rib I3 or on adjacent sides of the spacer strips. The inner edges of the covers I l and I2 are formed with similar dovetailed tongues engaging certain of the spacerY i strips. Y v i The operation of the binder maybe understood from the following:

The screws 23 may be removed to free the covers Il and l2. Then the loose leaf pages l1 may be stacked upon or removed from the stacking pins 24. The covers il and i2 may be re-connected with the back i6 by moving the stacked pages Il so that the studs i5 engage through the complementary perforations l of pages il. Then the screws 23 are re-engaged with the ends of the studs i5. t should be particularly noted that the angle members Si) protect the inner corners of the pages Il. The covers i i and l2 may be opened and closed because of the flexible areas 22. The flexible areas 22 comprise merely adjacent portions of the covering sheets 32 and 34.

In Fig. 7 a shorter stud l5 is illustrated to in dicate that the rib i3 may be provided with transverse studs of desirable lengths, depending upon the number of pages il' for the binder. When the number of pages are increased it is desirable that the studs be replaced with longer studs, and when pages are removed, smaller studs should be used.

The covers i I and i 2 may be supported in various laterally extended positions on the rib i3 by adding or removing spacer strips 2t. This .ar-

rangement permits adjustment to be made to better compensate the pages il of the binder. If the binder is provided with a large number of pages I'l additional spacer strips 2E are added, and if pages are removed then spacer strips 26 are removed.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the `right is reserved to all changes and modications coming within the scope of the invention as dened in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by `lilnited States Letters Patent is: Y
